从不同的PC检索图像

Question

我正在开发一个网站（HTML，CSS，PHP，JavaScript），需要访问不同的PC并获取图像。然后我想向任何用户使用我的程序显示这些图像。

例如，我想从我的电脑上打开pcA上的文件夹A并获取所有图像 该文件夹并将其显示在我的网站中。这可能吗？

这是我的代码：

$dir1 = "pictures/";
$dir2 = "pictures2/";
$dir3 = "pictures3/";

 $basedir = array(
    'basedir1' => $dir1 ,
    'basedir2' => $dir2 ,
    'basedir3' => $dir3 
   );

    function readGPSinfoEXIF($image_full_name)
    {
    if (file_exists($image_full_name) )
     {
       $exif=exif_read_data($image_full_name, 0, true);
       if ( !empty($exif['GPS']['GPSLatitude']) )
       {

         if(!$exif || $exif['GPS']['GPSLatitude'] == '') 
          {
           return false; 
          } 

          else 
           {
            $lat_ref = $exif['GPS']['GPSLatitudeRef']; 
            $lat = $exif['GPS']['GPSLatitude'];
            list($num, $dec) = explode('/', $lat[0]);
            $lat_s = $num / $dec;
            list($num, $dec) = explode('/', $lat[1]);
            $lat_m = $num / $dec;
            list($num, $dec) = explode('/', $lat[2]);
            $lat_v = $num / $dec;

            $lon_ref = $exif['GPS']['GPSLongitudeRef'];
            $lon = $exif['GPS']['GPSLongitude'];
            list($num, $dec) = explode('/', $lon[0]);
            $lon_s = $num / $dec;
            list($num, $dec) = explode('/', $lon[1]);
            $lon_m = $num / $dec;
            list($num, $dec) = explode('/', $lon[2]);
            $lon_v = $num / $dec;

            $gps_int = array($lat_s + $lat_m / 60.0 + $lat_v / 3600.0, $lon_s + $lon_m / 60.0 + $lon_v / 3600.0);

            return $gps_int;
           }//end of else
        }//end of if checking if GPS value is not empty
      }//check if file exists
    }//end of function
